For the nine T we wanted a special pipe , but it is perfectly homologated for road use! Steel connector with titanium silencer entirely handmade,in perfect moto gp style. It weighs about 2,8 kg lighter than the original and has a removable DB-Killer. It mounts easily in just a few minutes onto the passenger frame on the original anti-vibration grommet. If you want to remove the passenger frame and make the rear of the bike really aggressive, you'll have to buy our support code "1611 supp high". The sound will make you crazy,and the engine resposiveness ... as well!
